how to find size of object/variable? : sizeof()

sizeof() is provided by your compiler, and it tells you the size of the object you pass in as a parameter.

#include <iostream.h>

int main()
{
    cout << "The size of an int is:\t\t" << sizeof(int) << " bytes.\n";
    cout << "The size of a short int is:\t" << sizeof(short) << " bytes.\n";
    cout << "The size of a long int is:\t" << sizeof(long) << " bytes.\n";
    cout << "The size of a char is:\t\t" << sizeof(char) << " bytes.\n";
    cout << "The size of a float is:\t\t" << sizeof(float) << " bytes.\n";
    cout << "The size of a double is:\t" << sizeof(double) << " bytes.\n";

    return 0;
}

Output:The size of an int is: 2 bytes.
The size of a short int is: 2 bytes.
The size of a long int is: 4 bytes.
The size of a char is: 1 bytes.
The size of a float is: 4 bytes.
The size of a double is: 8 bytes.
